I have been using the 5 year orange coolant in my C3, did I make a bad decision.  I have had it in the car for some time now.  GM stuff.  I have the system down right now, so I can go back to green if I should.

Hi Joe, I'm not an expert on this, but I used the orange stuff for a while cause it claimed to be universally compatible (aluminum or iron blocks) and I have several different cars, and it seemed to disappear in the system, with or without leaks Confused. After hearing some negative info on orange, I switched back to a universally compatible green formula and all is well. I don't know, but I don't have any use for it. I'm a Prestone kinda guy Big%20smile. Good quality, no guessing.

I have used it in another vehicle and had problems with leaks, went back to green and problem solved. Unless the vehicle came with it, I'd stay green. My  2 cents.

Joe. There is a thread somewhere here talking about the disadvantage of using Dex-cool. In a nutshell, even the newer GM cars with Dex-Cool are having serious problem with intake leaks, and the stuff turning to mud, etc. There is absolutely no advantage in using Dex-Cool or any other long life antifreeze in an older car that should be flushed and filled every 2-3 years regardless of whats in it.
I say this by years of experience in this field.      Go green

For the most part, about the only advantage the non-ethlene glycol (green stuff) has is that it's less toxic should an animal drink any dripping or spillage.  Not that's it's non-toxic, simply less toxic.

Unless the car manufacturer specifies Dex-Cool or something other than ethlene-glycol, I wouldn't use it.

Thanks Terry, this is the kind of info I need.  I have had the orange stuff, GM, in the car for a while and have had my share of small leaks, some I could never find, was trying to extend the flush interval.  When I bring the system back up I will refill it w/ just water and run it for a while and drain, hopefully that will get rid of most of it.  Will go back green, what brand do you recommend and how often should I flush?  Keep in mind this car sits allot, but other than right now I run it every two weeks, no longer than three at the most.

 

Just changed the harmonic balancer and saw obvious signs that the water pump had been leaking from the lower weep hole for quiet some time.  Pulled pump and all hoses.  Not going back w/ the heater hoses, just 4 more points to corrode and leak.  Planning on filling the heat core w/ coolant mix and run a hose from tube to tube which is going to be fun.  I donít want the heater core to go bad unless you think I should just drain it?

Hey Joe. As I posted in Heater Hoses, its not a bad idea to leave a little coolant in heater to keep it from drying out. Make sure you use a mixture, because believe it or not straight antifreeze is very corrosive. As far as Dex, it is ethylene glycol with different rust inhibitor package than green. Dex uses what is called O.A.T. or Organic Acid Technologies, where green uses silicates. If you want to know facts about Dex, Google Dex-Cool lawsuits and see what comes up. My favorite pics are http://www.sancarlosradiator.com/dex-cool_pics.htm

Well I can say my hoses don't look nothing like that, they were very clean.  A little residue in the radiator.  Will runing w/ clear water remove what is left in the motor?  Printed the info, will read soon.  If needed, I will flush in 6months again just to get it out of the system.

I think if you flush the system real good until the water comes out clear you should be OK. You really don't want to run with just water for very long. Plain water has a lower boiling point, plus you need the rust inhibitors. Make sure you mix antifreeze at least 50/50. Actually I prefer around 60-70% antifreeze. Its not a bad idea to use distilled water especially if your water has a lot of minerals in it.Wink

My camaro, the wifes car ,always call for distilled.  So the best thing is for me to do a flush w/ the mix correct, not just clear water?  What brand coolant do you recommend?

I found this very interesting. recently my sons 98 camaro was losing antifreeze. no leaks, nothing on the ground. I took it to a service station
and the mechanic said the intake manifold gasket was ng, and it was a common problem on these cars, gm used inferior gaskets, the radiator also had that red mud in it. We had the gasket replaced and the dexcool antifreeze. about a month later the engine blew, it had about 117,00 miles. the mechanic said antifreeze probably got into the engine. We had the engine replaced with a remanufactured engine from jasper engines, and put the dexcool back in. Was the dex  what caused the gasket to go,or what the mechanic said about tjhe inferior gaskets true. I'm wondering should we flush this crap out and replace it with prestone. Prestone makes a coolant that replaces the dex or should I replaced it with regular antifreeze.

You just need water to flush out old A.F. Then try to get out as much water as you can so you can get proper mix. You can pull lower hose and let it drain. You can also blow out the water with air, but you have to be careful not to use too much pressure.

Hey Tony. Your mechanic is right. In certain motors Dexcool turns to sludge and attacks the gaskets. Yes GM used an intake gasket that was inferior when using  Dex. The aftermarket gaskets are made of a different material. I am still baffled why this is only true with some motors and not others. The Vortec 4.3 and the 3.8 are the ones I see the most. By all means get the Dex out and replace with Green. Most green antifreeze comes from the same boat, however its not bad to stick with the big 3, Preston, Peak, Zerex. The drop in replacements are suppose to be compatible, I haven't seen problems contradicting that. I do use Peak long life in newer cars after the Dex has been flushed.
Another interesting site.

Already pulled all the hoses when I pulled the water pump.  I will put back together, fill and flush in my garage.  Will push as much as possible out with air also.  Will refill w/ green and flush again in about 6 months just to make sure I got most of that stuff out.  The only green stuff Advance Auto had was Peak brand.  Most stores are stocking alot of the extended life stuff.  Thanks again Terry for all our adivce.

Not a bad idea Aaron. Reminds me of the time I got an old beater in here that was overheating. Well we flushed out some mud and crap like I ain't never seen before, and man did it stink. I asked what he put in there. Well, he told me that a guy told him you can stop a leak with raw eggs. Dint work so's I tried oatmeal.Still leaken and a bubba told me to try pepper. So's I put in, get this, a pound of pepper!! Well, I says ya know that's not a bad thing cause iffin the stuff don't stop the leak y'all kin sit long side da road drain the lower hose n have breakfast.Wacko
Throw in a lil Choo Choo Cherry Funny face, n ya got da drink ta go wid it.Rolling%20On%20The%20Floor%20Laughing

Hey Tony. Yes there is an antifreeze compatible with Dex & other colored coolant. The only time I us it is to add to a system that I'm not sure whats in it. If your flushing out all the Dex, personally I would replace with just regular green. Now keep in mind that rust inhibitors are "a preventive" against corrosion. Once the damage has been done, there's not much you can do to get all the sludge out. If you replaced the motor, its probably not to late to get the inhibitors working,. because the system should be fairly clean. Hope this helps. Terry

Yes, thanks for the info. We also have a new radiator, because the mechanic suggested a new radiator because of the sludge. That orange crap really makes a mess
